<p>2:2 Pulldown detection uses the comb factor measurement to determine whether 
the material was sourced from film or from video.  The default settings have been
found to work with a wide range of inputs but there are problems with some highly
detailed images.</p>

<table border="1">
<tr>
<th>Setting</th>
<th>Default</th>
<th>Description</th>
</tr>

<tr>
<td>Pulldown Threshold Low</td>
<td>40</td>
<td>This is the percentage drop in comb factor that will be considered to be 
a candidate film mode.</td>
</tr>

<tr>
<td>Pulldown Threshold High</td>
<td>10</td>
<td>This is the percentage increase in comb-factor that will be considered 
evedence that we are no longer in film mode</td>
</tr>

<tr>
<td>PAL Video Mode</td>
<td>Dependent on CPU selection in general hardware dialog box</td>
<td>This is the mode that will be used when film mode has not been detected</td>
</tr>

<tr>
<td>PAL Pulldown Repeat Count In</td>
<td>3</td>
<td>Number of times film mode must be spotted in a row before a switch to film mode</td>
</tr>

<tr>
<td>PAL Pulldown Repeat Count Out</td>
<td>1</td>
<td>Each time bad pulldown is encountered the count is decremented starting at 
"PAL Pulldown Repeat Count In", once the count reaches this 
value then we go back to video mode.</td>
</tr>

<tr>
<td>Max Calls to PAL Comb Method</td>
<td>20</td>
<td>If we have tuned off "Bad Pulldown Filter" then this is the number of calls
allowed to the bad cadence method before switching back to video mode.
</td>
</tr>

<tr>
<td>PAL Bad Cadence Mode</td>
<td>Greedy Low Motion</td>
<td>If we have tuned off "Bad Pulldown Filter" then this mode is activated when 
 bad cadence is detected.</td>
